Online Seminar: Deterministic Benchmarking of Quantum Gates

The conventional methods to benchmark the quantum gate errors, such as randomized benchmarking (RB), overlook the role of coherent errors known to be one of the most detrimental sources of error, hindering us from the realization of high-fidelity quantum algorithms. This seminar covers a latest research from Prof. Levenson-Falk and and Prof. Lidar Labs at University of Southern California. We present deterministic benchmarking - a new method based on simple dynamical decoupling sequences to reliably capture both coherent and incoherent errors of quantum gates. This method provides insights on how to mitigate these errors and opens a path towards successful implementation of error-correcting algorithms, (arXiv:2407.09942v1).

The seminar is presented by Daria Kowsari, with Michal Goldenshtein co-hosting the event.
